Bucky hadn't heard Becca come home. Which was unusual, since Bucky tended to be hyperaware of things. But Moo and Clint were distracting, and add in the drug that was mellowing him out and the world just seemed fine enough that Bucky didn't have to clock what all the sounds in the next room might be. He looked up at the knock though, blinking in surprise as he saw Steve - Becca watching from behind him and then slinking off.
Bucky snickered a little to himself. If Becca still talked to him, he'd have given her a hard time about the family weakness for Rogerses. She'd had a thing for Steve since she was like nine, back when he was still skinny and angry.
Now he was just giant and angry, so Bucky guessed it made sense.
"Hey, Stevie," Bucky said, smiling at him. There were reasons they were supposed to not hang out, and reasons they should be strange and strained when they did - but fuck it. Bucky felt good and he didn't want to be, and Clint already knew they were friends. "C'mon in. Meet the girlfriend Clint's trying to make me take off his hands."
Bucky started to laugh again. "Ace," he repeated. "What the fuck, Barton?" Nevermind he'd just called Steve Stevie, like they were twelve and Bucky was prodding fondly at him.
He blinked. Oh, fuck yeah. "Steve, you need to try some of this," Bucky said, holding out the tea cup. "Swear it doesn't make you stupid or ... anything else." Horny, which Steve had gotten last time, which was hilarious at the moment. "It's just nice. Come sit. This is Moo. She's a cow but she looks like a kitten, so don't let her fool you."
